SELF-CONTAINED ROLLER-BEARING.

Specification of Letters Patent. Patented Apr, 12, 1910, Applicationfiled March 26, 1909.

Serial No. 485,969.

To all cvhom it may concern.

Be it known that 1, CHARLES S. LOCK- wooD, a citizen of the UnitedStates, residing at 289 Market street, Newark, county of Essex and Stateof New Jersey, have in-*'- vente certain new and useful Improvements inSelf-Contained Roller-Bearings, fully described and represented in thefollowing specification and the accompanying words, it serves both tocarry the load and resist end thrusts.

The invention includes a hub having two opposed tapering seats withtapering rolls fitted thereto and a casing formed in two annular partsada ted to embrace the outer sides of'the ro ls, and the parts of thecasmg secured together so as to retain all of the fixtures therein, andthus form a selfcontained roller bearing. The contiguous ends of therolls are preferably beveled and fitted to roll in contact with oneanother, and a doubly conical cage is preferably employed to guide therolls in their movement v within the casing.

A modification of the invention provides a raised collar at the junctionof the conical seats upon the hub, and the rolls shouldered to traveladjacent to such collar with their contiguous ends in contact, thecollar serving positively to prevent any longitudinal displacement ofthe rolls. v

The invention will be understood by reference to the annexed drawing, inwhich Figure 1 is an end view of the roller bearing with the nearer halfof the casing removed; Fig. 2 is a section on line 22 in 1 of all theparts excepting the rolls; Fig. 3 1s a similar section of one side ofthe casing; Fig. 4 is an external view of the op the junction of thedoubly conical seats; Fig.

10 is a section on line 1010 in Fig. 9, Fig. 11 is a side view of one ofthe rolls shown in Fig. 9-; Fig. 12 is. an inside view rolls in contactwith one another.

of the right-hand half of the casing shown in Fig. 9; Fig. 13 is an endview, and Fig.

14 an edge view of one-half of the cage with lugs thereon to hold therolls upon the conical seats when removed from the casing.

The convex conical seats a are shown formed upon the hub in Figs. 2 and8 with their bases joined and cylindrical seats 6 extended from theirouter ends to support the inner flanges 0 of the cage. The rolls d aretapered in the same proportion as the seats upon the hub, and aspressure upon such tapering rolls has a tendency to slide them endwisesu'ch sliding tendency is resisted 'by rotating the larger ends of theTo increase the wearing surface upon the ends of the rolls, their largerends are formed with conical surfaces e which roll upon one another whenthe rolls are held upon their seats by the casing. The casing is shownformedof two rings f and g, which are connected by annular flanges f and9' having screw-threads h to engage one another, and

are provided with concave or tapering seats a to embrace the rolls, andwith oil-retaining flanges h extended inwardly from their outer endsclose to the .hub. The flanges 71. form a pocket in the bottom of thecasing which prevents the lubricant from escaping. A'notch '21 is shownin the flange g and a series of holes j in the flange f, and a screw 70is shown in Figs. 2 and 3 inserted in one of the holes and its headfitted to the notch 2', as shown in dottedlines in Fig. 4. Suchengagement of the head with the notch prevents the parts of the casingfrom rotating upon one another when adjusted, and ,the series of holes jpermits the parts of the casing when thescrew k is removed, to be turnedupon one another in a fixed degree and secured in their new adjustmentby reinsertin the screw. To secure a fine adjustment 0 the casingwithout greatly multiplying the screW-holes j, the flange g u on thecasing may be formed with a note additional to the notch 2', as shown inFig.

4:, and spaced to secure the casing art 9 in positions intermediate tothose e ected by using the notch The additionof the single notch g thussecures the same efiect as doubling the entire number of tap-holes y.Holes Z are shown upon the edges of the.,parts in Fig. 2 for turningthetwo halves of the casing by suitable wrenches. A

, To guide the rolls in their movementand hold their axes in fixedrelation to the axis of the shaft upon which the bearing is used,

- I provide a doubly conical cage formed in tion.

two similar parts, each having an outer flange 0 adapted to rest uponthe cylindrical.

.side for the flanges m, while the ends of the rolls rotate in contactadjacent to the seat a.

The cage is applied to the hub by fastening the halves upon theopposite, ends of the same, with the flanges main contact and securingsuch flanges together by screws or rivets p, as shown in Fig. 2.

Where the hub is largest at the middle, as in the present construction,the rolls are also largest at their contiguous ends, and the casingcannot be applied except it be made divisible and the parts providedwith concave seats to embrace the rolls, and suitably united together tofit snugly upon the rolls when in operation.

With the flanges f and g screwed together and locked in their adjustedposition by the screw k, the casing is entirely rigid and can be securedin any part of the mechanism in which the roller bearin is used tosupport a rotatin axle, the hub being secured upon the a e to rotatetherewith.

In the modification shown in Fig. 9, a raised collar 1" is formed at thejunction of the conical seats upon the hub, and the inner corners of therolls are arranged to rotate adjacent to this collar which thus preventseither of them from moving longitudinally upon its seat. To bring theends of the rolls in contact, they are formed with bosses 8 upon theirinner ends having conical seats I? formed thereon which contact with oneanother above the periphery of the collar 7'. The bosses thus resist thenatural thrust of therolls toward one another, while the collar 1'resists any tendency of the rolls to move from their normal path.

Figs. 9, 10, 13 and 14: show the cage formedv with lugs u at theopposite sides of the openings 0,. which lugs are curved over the outersides of the rolls, as shown in Fig. 10, and thus prevent the rolls fromfalling out of the cage when the casing is removed. As it is sometimesnecessary to remove the two rings which form the casing from one anotherto clean out 'the same or examine the condition of the bearing, it isobvious that the rolls would fall out of the bearing unless thusretained by the cage.

between the spread ends 0 series of rolls, as I have claimed the same ina co-pending application No. 523,285 filed Oct. 18, 1909 with title,Self-contained roller-bearing with locked casing.
